As a developer, i love working with Sanity as a "Headless" CMS. It's easy to set up and configure, and especially in Sanity Studio v3, it's so much easier to fully customize how the Studio (the CMS admin interface, a self-hosted react app) looks and works.
In my opinion, Sanity is the best solution for managing structured content in single source of truth, making it a great foundation to build any digital product on top of.
Also the Sanity community is great – really friendly and helpful!
